Procurement Notes
Verify the specific manufacturer lot code and RoHS compliance status directly with the supplier, as historical data indicates non-RoHS variants may exist. Confirm the package type matches the required through-hole footprint before ordering. Ensure the requested quantity aligns with the manufacturer's minimum order requirements and lead times.
Selection Notes
Select this component when high voltage blocking capability and moderate current handling are required in a through-hole package. Consider the 1 kV reverse voltage rating for mains-derived supplies. Evaluate the thermal management requirements given the 3 A continuous current rating and the specified operating temperature range.
Part Context
This part belongs to the standard rectifier diode category from Microchip Technology. It utilizes a DO-41 style axial leaded package suitable for PCB mounting. The device is classified under Diodes & Rectifiers and serves as a fundamental component for AC-to-DC conversion and polarity protection in electronic circuits.
Replacement Considerations
Consult official substitution lists for equivalent 1 kV, 3 A through-hole rectifiers. Verify pinout compatibility and thermal characteristics before replacing.
